Environmentally Friendly Water Treatment

Nooter/Eriksen expertise has always been on good quality water, in order to meet the stringent requirement needed for a boiler feedwater. Nooter/Eriksen decided to extend its chemistry expertise experience in a broader water quality management in power plants and other industrial complexes. This will reduce the operative cost of the plant but also substantially reduce waste of water and limit contaminants to the environment with a net improvement from an environmental point of view.

Nooter/Eriksen will act as a service provider to the customer in order to provide a tailor-made solution reducing the cost of water and chemicals needed for their treatment. Nooter/Eriksen will utilize the HydroFLOW equipment with Hydropath technology in optimizing the plant performances. Nooter/Eriksen and HydroFLOW entered into an exclusive agreement to supply HydroFLOW equipment in most of power plants and refineries in North America.

Nooter/Eriksen Water Solutions

As part of our commitment to improving our customer’s bottom line, Nooter/Eriksen is now offering an innovative cooling tower water conditioning technology which has proven to optimize the use of chemicals, make-up water, and maintenance at your combined cycle power plant, refinery, or other large scale industrial facilities.

Nooter/Eriksen will combine its remarkable experience in power plants with Hydropath Technology which has over one million units worldwide from home size to large scale. Established in 2010, HydroFLOW is the sole US distributor of these water conditioning devices and in 2020 Nooter/Eriksen and HydroFLOW entered into a mutually exclusive cooperation agreement.

The Hydropath/HydroFLOW technology has been validated in the past 10 years on domestic and international cooling towers at refineries, hospitals, government facilities, hotels, wastewater treatment plants, and other industrial facilities. Some examples include Nellis Air Force Base, a Phillips 66 Refinery, and Kaiser Permanente Hospital.


  • Prevents new scale

  • Controls bacteria, algae, and biofilm

  • Inhibits corrosion
  • Reduces make-up water requirements
  • Optimized/reduces the use of chemicals
  • Reduces maintenance
  • Saves energy


The HydroFLOW water conditioning device induces an electrical signal into the entire cooling water system which alters the arrangement of dissolved ions in solution causing them to cluster together in close proximity but not yet in solid/precipitated form. Changes in temperature or pressure that would normally result in solids scaling out on the piping and heat transfer surfaces now result in formation of sub-millimeter solids/precipitates within the flowing liquid. An additional benefit is that the device actively controls bacteria such as legionella, algae, and biofilm. As they pass the device the bacteria are charged by its action. The charged bacteria are quickly surrounded by pure water where osmosis begins to force water into the cell causing it to burst. The cells can also be ruptured by cell lysis and irreversible electroporation. These actions greatly reduce the ill effects of scale and biofouling. All of this occurs from the signal that is harmless to humans and the equipment in the cooling tower system.


Nooter/Eriksen understands this is a significant change from your current system. As such, we would like to come to your facility and meet with your management and technical teams to present this technology in more detail. Nooter/Eriksen is very excited about this new technology and we believe the HydroFLOW device will increase your cooling tower performance while saving cost.

Nooter/Eriksen recently installed the largest HydroFLOW equipment of North America.
